tRPC (Type-Safe API Layer)

Overview

tRPC enables end-to-end typesafe APIs by sharing TypeScript types between client and server. No code generation, no schema files—just TypeScript.

Version: v11.7+ (2024-2025)
Requirements: TypeScript ≥5.7.2 with strict mode

Key Benefit: Change a procedure's input/output → TypeScript errors appear immediately on client.

When to Use This Skill

✅ Use tRPC when:

• Building full-stack TypeScript apps (Next.js, React + Express)
• You control both client and server code
• Need type-safe API without GraphQL complexity
• Want automatic request batching and caching
• Building internal APIs, dashboards, admin panels
